Abstract
A device for developing an electrostatic latent image located on a movable image carrier, the developing device having a toner feeder for feeding toner particles from a toner reservoir and for electrically charging the particles, and a rotatably mounted developing roller having a surface for accepting the charged toner particles, includes a device spaced from the surface of the developing roller for generating an alternating electric field actable upon the toner particles; and a method for operating the developing device.
